Master/slave DNS server query

I was wondering what the best approach would be to have a set-up in which:

1) The master DNS server is a Windows box running Simple DNS Plus.
2) The slave DNS server is the cPanel box.

Going through the options in WHM it would see mthe best way would be to set-up the cPanel box manually (which isn't a problem, it would just have been nice to have seen support for master/slave DNS servers which are NOT cPanel based).
